Abstract
The utility model relates to a plastic bottle blowing machine, composed of a base, a mould frame, a cylinder for opening and closing a mould plate, a link mechanism, a half-mould die, a ram, a stretching mechanism, a gas control mechanism, an electric control mechanism, etc. The utility model is characterized in that a clamping plate for a front half mould, and a supporting plate are fixed on the mould frame; a clamping plate for a back half mould is connected with the bottom of the ram through a fixed connecting block, and the clamping plate for a back half mould can be simultaneously moved with the ram. the machine has the advantages of reasonable improvement and design, and simple structure; the utility model also has the advantages that deformation and displacement can not occur after moulds are matched; the phenomenon of expanded mould can not occur when the mould is blown with high-pressure gas (2.5Mpa); the top head of the stretching mechanism and the die can be centered accurately in time, and the shaped quality of plastic bottles can be ensured.
Description
The utility model relates to a kind of used equipment of shape that plastic parison blow out is required, i.e. blower for plastic bottle.
Existing blow molding apparatus and clasp mould mechanism kind are a lot; the directed blow molding machine of a kind of two-step method biaxial tension is disclosed as Chinese patent CN2127656Y; these facility have clamping mechanism; seal drawing mechanism and electric program automatic control is partly formed; it is characterized in that; draft cylinder is fixed on the middle mould template; the piston rod of draft cylinder upwards stretching fixed head and the stretching bar through being fixed on the dovetail groove fixed head is connected as a single entity; the stretching bar upper end that is positioned at stretching bar fixed head below is fixed with the stretching shock-proof spring, is with sheath on the guide pillar between the middle cross template respectively.Chinese patent CN2152653Y discloses a kind of blow molding apparatus for another example; CN2188014Y discloses a kind of clasp mould mechanism that is used for blow molding apparatus; CN2199039Y discloses a kind of matched moulds member of blow molding machine.But above-mentioned blow molding apparatus all is not suitable for blowing high-quality super-huge (5 gallons) plastic bottle.
The purpose of this utility model is: provide a kind of blower for plastic bottle that can blow normal system high-quality super-huge (5 gallons) plastic bottle by the improvement to existing bottle blowing machine.
Bottle blowing machine by following proposal can be realized the foregoing invention purpose.This blower for plastic bottle is made up of base, mould bases, template folding cylinder, linkage, half module mould, ram, drawing mechanism, gas, electric control mechanism etc., it is characterized in that:
Preceding half module grip block is fixed on the mould bases, and the back mold half grip block is movable; The one side connecting rod and the back mold half grip block of linkage are connected, and its opposite side connecting rod and gripper shoe are connected, and gripper shoe is fixed on the mould bases;
Back mold half grip block top is connected with the ram bottom by fixedly connected.
Be provided with push rod between the upper outside of preceding half module grip block and the mould bases.
The utlity model has the advantage of two aspects:
One, adopted preceding half module grip block and gripper shoe have been fixed on structure on the mould bases, and preceding half module grip block outer upper is gained in strength by push rod is set, rigidity has guaranteed can not be out of shape after the half module mould is finished matched moulds, can not displacement, so guaranteed not take place the mould phenomenon that expands.
Two, adopted drawing mechanism is fixed on the ram, ram is fixedlyed connected the structure of synchronous interaction with the back mold half grip block, and the centering that has guaranteed the top of drawing mechanism and half transverse mode tool accurately and timely makes and moulds bottle and be shaped and can reach high quality standards.
Fig. 1 is the utility model structural representation.
Explain below by 1 pair of most preferred embodiment of accompanying drawing.As seen from Figure 1, this bottle blowing machine is made up of base 7, mould bases 6, template folding cylinder 5, linkage 4, half module mould, ram 2, drawing mechanism 1, gas, electric control mechanism etc.
Before half module 3 is contained on the half module grip block 8, preceding half module grip block 8 is fixed on the bottom of mould bases 8 by backup plate 13, and push rod 12 is fixed between mould bases 6 and the preceding half module grip block 8, to increase intensity, the rigidity of preceding half module grip block 8.Back mold half grip block 9 is movable, and a side connecting rod and the back mold half grip block 9 of linkage 4 are connected, and its opposite side connecting rod is fixedlyed connected with gripper shoe 10, and gripper shoe 10 is fixed on the crossbearer 6 by backup plate 13.
Back mold half grip block 9 tops are connected by fixedly connected angle bar 11 with ram 2 bottoms, and the two is synchronized with the movement.
During operation, the half module 3 before the plastic parison of heating put on the half module grip block 8, then, back mold half grip block 9 is being with half module 3, drawing mechanism 1 to carry out the matched moulds motion.After matched moulds was finished, the connecting rod of linkage 4 reached the dead point point-blank, its support force maximum; Centering has been realized in time, exactly with the half module mould in the top 14 of drawing mechanism 1 simultaneously.
Claims (2)
